Description

Technical Field

[0001] The utility model relates to the technical field of steel cord processing, in particular to a protective cover for welding broken steel wires. Background Art

[0002] Steel cord is a twisted wire made of high-strength steel wire, widely used in tire and machinery manufacturing. Wire breakage is a common problem during its production process, requiring welding to compensate for the insufficient cord length caused by broken wires. After welding, the welds are typically forged. Forging welds is a crucial step in improving their strength and stability. Forging eliminates internal defects and stresses, improving their density and toughness.

[0003] At present, the forging of welds is achieved through a forging device on the welding machine. The forging device is on one side of the welding machine. The forging device includes a base and a hammer head. The hammer head can move downward to hit the base to shape the weld on the base. Due to the high forging force and fast inching speed, in order to accurately hit the weld position during forging without accidentally damaging the cord, the distance between the weld and the hand is close, which poses a risk of accidentally injuring the fingers.

[0026] In order to better understand the technical content of the present invention, specific embodiments are given and described below with reference to the accompanying drawings.

[0027] Combine Figure 1 and Figure 2 As shown, when the steel wire is broken, the two broken wires are welded by a welding device. After welding, the weld point is forged on a forging device transferred to the welding device. One purpose of forging is to improve the physical properties of the weld point, and the second purpose is to improve the shape of the weld point. During forging, it is necessary to control the weld point to be on the base, and the hammer head above periodically moves downward to hit the base, thereby hammering the weld point. During hammering, it is necessary to manually control the angle of the steel wire so that the weld point is hammered into an ideal shape.

[0028] Since the position of the steel wire and the welding point needs to be manually controlled, the hands are close to the base, which increases the safety hazard. Figure 3 As shown, the present application proposes a protective cover 10 for wire break welding, which is adapted to a forging device, and especially surrounds the base 3 and the hammer head 4 to improve safety.

[0029] Combine Figure 4 As shown, the utility model proposes a protective cover for broken wire welding, including a cover body 1 and a connecting structure 2. The cover body 1 is configured as a tubular structure with openings on the upper and lower sides. The connecting structure 2 is connected to the outer wall of the cover body 1 and is located at the bottom of the cover body 1.

[0030] Preferably, the cover body 1 is made of a transparent material, such as PC, PP, or PMMA.

[0031] Since there is a plane between the upper edge of the bottom of the base 3 of the forging device and the lower edge of the upper part of the hammer head 4, the cover body 1 is designed to be tubular so that it can be inserted between the upper edge and the lower edge to surround the base 3 and the hammer head 4. Specifically, the connecting structure 2 is constructed in a sheet shape with screw holes on the surface, and the cover body 1 can be fixed to the bottom of the base 3 by screws.

[0032] Since the height of the cover 1 is much higher than the distance between the base 3 and the hammer head 4, the base 3 and the hammer head 4 of the forging device are required to be located within the cover 1 after installation. Therefore, the cover 1 is further provided with a second notch 12 corresponding to the position of the hammer head 4 and a third notch 13 corresponding to the position of the base 3. The second notch 12 and the third notch 13 are facing the side of the forging device away from the user.

[0033] The second notch 12 extends downward from the upper edge of the cover body 1 , and the third notch 13 extends upward from the lower edge of the cover body 1 .

[0034] Preferably, the height of the second notch 12 is higher than the height of the hammer head 4 , and the height of the third notch 13 is higher than the height of the base 3 .

[0035] So, combined Figure 5 As shown, the cover body 1 can be moved horizontally to between the upper edge of the bottom of the base 3 and the lower edge of the upper part of the hammer head 4. The base 3 can enter the cover body 1 through the third notch 13, and the hammer head 4 can enter the cover body 1 through the second notch 12.

[0036] Furthermore, the cover body 1 is provided with a first notch at a height corresponding to the upper edge of the base 3, and the first notch is toward the side of the forging device facing the user. In this way, the user can hold the steel wire with the welding point and move it through the first notch into the cover body 1, especially so that the welding point is on the upper end surface of the base 3.

[0037] In an optional embodiment, the first notch includes two forged areas 15 and one passing area 14 , and the forged areas 15 on both sides are arranged at both ends of the passing area 14 .

[0038] The height of the first notch in the forging area 15 is greater than the height of the passing area 14 .

[0039] In this way, the user can hold the steel wire and move it from the passing area 14 to the forging area 15. Since the forging area 15 is high, it is convenient to adjust the angle of the steel wire in this area, so that the welding point is conducive to being shaped during forging.

[0040] The connecting line between the two forging areas 15 passes through the upper edge of the base 3 .

[0041] In this way, when the steel wire passes through the forging area 15 , the welding point of the steel wire is easily located on the base 3 .

[0042] Preferably, the forged area 15 is designed to have a circular or elliptical contour, and the height of the forged area 15 is less than 10 mm.

[0043] It should be understood that the circular or elliptical profile is conducive to providing the steel wire with a larger angle adjustment space in the area, and the size of the area is not large enough to allow fingers to enter, so as to avoid the fingers being pressed by the hammer head 4, thereby improving safety.

[0044] Furthermore, the cover 1 is configured to be narrower in width than in length, wherein the transverse direction of the wire is the width direction, and the direction in which the wire extends in and out is the length direction. This allows the fingers to be closer to the base 3 from both sides, which is beneficial for controlling the angle of the welding point.

[0045] In an optional embodiment, the cross-sectional shape of the cover body 1 is elliptical.

[0046] In an optional embodiment, the cross-sectional shape of the cover body 1 is square, and the width of the cover body 1 in the transverse direction of the steel wire is smaller than the length of the steel wire in the direction of extension / extension.

[0047] In combination with the above embodiments, the protective cover proposed by the present invention can be adapted to the existing forging device. By slotting the rear part of the cover body, the cover body can be assembled between the hammer head and the base of the forging device, and surround the hammer head and the base. The front part of the cover body is slotted, so that the user can hold the steel wire through the slot at the front to make the welding point enter the base, and the posture of the welding point can be adjusted so that the welding point can be hammered to a suitable angle. At the same time, the cover body also plays a protective role to prevent fingers from being hammered by the hammer head, and has high safety.

[0048] While the present invention has been described above with reference to preferred embodiments, this is not intended to limit the present invention. Persons skilled in the art will readily appreciate that various modifications and variations may be made without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
